当试图在Android-Studio中为Genymotion提供午餐时,会出现以下错误:我已经发现这个genymotion-invalid-path-vboxmanage-and-initialize-engine-failed但是这并没有解决我的问题.

20:34:29 Genymotion: Loading Genymotion library
20:34:29 Genymotion: Genymotion directory: C:\Program Files\Genymobile\Genymotion
20:34:29 Genymotion: Trying to initialize engine
20:34:29 Genymotion: Invalid path: VBoxManage
20:34:29 Genymotion: Initialize Engine: failed

对此有任何想法.

I'm using the objectaid eclipse plugin to get diagram class for my java project.

I can't find a way to zoom the view, I can zoom out by pressing Ctrl + "-", but I can't zoom in by pressing Ctrl + "+".

Have any one idea?

我想从结尾到开头迭代一个 unordered_set：

unordered_set<Expression*> BlocExpressions;

for(auto it=BlocExpressions.end(); it != BlocExpressions.begin(); it--){   

                //do some work

            }

但是没有运算符 -- 声明。

那么，我应该对 -- 运算符进行编码，还是有办法做到这一点？

我有这个函数返回一个字符串:

string getStringFromFile()
    {
    ifstream in("in.txt");
        ofstream out("out.txt");
        std::string line;
        while(getline(in,line)){
        if(line.empty())
              line="http://www.google.com/";
        }

        return line;
    }

尝试调用该getStringFromFile函数时,它返回语法错误(Error : identificator not defined).

CreateWindowEx(0, _T("EDIT"),
                       _T(getStringFromFile()),
                       WS_CHILD | WS_VISIBLE | WS_BORDER,
                       260, 10,
                       200, 20,
                       hWnd, NULL, hInst, NULL);
